The purpose of this study was to determine if dual enrollment credits affected time to completion for commuter community college students in Suffolk County, New York when compared to students from the same geographic area that did not have dual enrollment credits. High school students take dual enrollment courses usually during their junior or senior year to earn both high school and college credit. The second purpose of the study was to determine if there were gender differences in time to completion for commuter community college students with dual enrollment credit. The third purpose of this study was to determine if there were differences in time to completion among ethnicity for commuter community college students with dual enrollment credits. This study employed longitudinal data collected from the community college's student enrollment records. The subjects in the study were traditional first-time, full-time freshman enrolled in the commuter community college the first fall semester after graduating from high school. The fall semester selected was fall 2013 because it was expected that a traditional full-time student would graduate from a community college in two years (100% time to completion). Study requirements were: students must have attended a public high school located in Suffolk County, New York; and, students had graduated from their high school in June 2013 and enrolled in the community college in the fall 2013 semester as a first-time, full-time student. The results of this study add to the existing literature on dual enrollment programs and the attainment of a postsecondary credential, in particular for the community college sector. Community colleges traditionally have open door policies which can allow academically weak students to enroll thus impacting their ability to persist and graduate. Results of this study indicate a positive effect for students with dual enrollment credit. Among gender female students with dual enrollment credit graduated sooner than male students with dual enrollment credit. Among ethnicity, nonminority students with dual enrollment credits graduated sooner than minority students with dual enrollment credits.
